How does a capacitor store energy?
Capacitors store electrical energy when connected to a power source. The stored energy is a result of the electric field established between the two plates of the capacitor, separated by an insulator or dielectric. Capacitance (C): The ability of a capacitor to store charge per unit potential difference.
How does a dielectric affect a capacitor?
Dielectric: A dielectric is an insulating material that can be polarized by an electric field, meaning it can store electrical energy. When placed between the plates of a capacitor, dielectrics increase the capacitor's ability to store charge and energy, affecting the energy stored in capacitors and their combinations.
How does capacitance affect energy stored in a capacitor?
Capacitance: The higher the capacitance, the more energy a capacitor can store. Capacitance depends on the surface area of the conductive plates, the distance between the plates, and the properties of the dielectric material.
